I have the same truck, just 5 years older.
They do not have a distributor. They have ford's EDIS (electronic distributorless ignition system) consisting of the engine computer, Ignition control module, and in the dual-plug 2.3's case, two ignition coils.
Get yourself a haynes manual and read how to diagnose these parts.
The ICM is kinda pricey but the auto part stores should be able to test it for you for free. My guess is that the ICM is fine. Ford computer parts rarely ever fail.
To test the timing, disconnect the SPOUT connector (which grounds the SPOUT circuit and puts the system in open loop operation) and verify that ignition timing is 10 degrees BTDC. If it is and truck runs like crap, then ignition parts need replacing. If it isn't, then the timing belt is on wrong and ignition parts are probably fine.
If the ignition timing isn't correct in closed loop operation (SPOUT circuit disconnected), I'd look at the coils. I recently had one go bad on my ranger. The tachometer read half of what it should, the engine ran like crap, and the computer threw a code stating that the SPOUT circuit was grounded and the ingition was in open loop operation at constant 10 degrees BTDC timing.
Go pick up a couple coils from a junkyard (they go for $10 a piece around here) just make sure they look good, chances are very high that they are good. They can be from any ranger 89-97 or mustang 91-93.
Also make sure the MAF he has on there is from a EEC-V (1995+ computer system) 2.3 ranger. If it's not, then the A/F ratio will be all messed up.
www.therangerstation.com has a lot of good tech and couple really smart 2.3 guys. I'd take a look over there.
And by the way, 185000 miles is nothing on a dual plug 2.3. That thing is just getting broken in!!!
